SHAFT-CLUTCH.

Specification of Letters Patent.

Application filed November 29, 1904. Serial No. 234,727.

means of screws 11 or in any other suitable manner to turn with saidloose member, and obviously power may be transmitted either from theshaft to said wheel or from said wheel to the shaft without affectingthe nature of my invention.

The member 6 of my improved clutch, which is fast upon the shaft 2,comprises a cross-piece 12, set upon the shaft, as by screws 13 13, andprojecting at its ends 14 14 on diametrically opposite sides of saidshaft. Each of said arms 14 is slotted, as at 15, and pivoted in saidslot upon a screw 16 is a lever 17, which is thus adapted to swing in aplane passing through the shaft 2. The said crosspiece 12 is arrangedupon the shaft 2 next the loose member 5, and the outer ends of thelevers 17, or. ends farthest from the shaft, have extremities 18,adapted to engage the ratchet-teeth 9 upon said loose member, as shownin the drawings. It will be understood that when said extremities engagethe ratchet-teeth, as shown in Fig. 1 more particularly, the engagementis positive and the two members of the clutch must turn together withoutslipping or lost motion.

For operating the said levers 17 to swing them into and out ofengagement with the loose clutch member 5 their inner ends 19 areconnected by links 20, extending parallel with the shaft 2, to a sleeve21, which is slidable upon the said shaft. Said sleeve has an exteriorcircumferential slot or recess 21 which receives the extremities 22 of aforked operating-lever 23, and thus as the said forked end of the leveris moved longitudinally of the shaft the sleeve 20 is correspondinglymoved and the levers 17 17 swung accordingly. Preferably a spiral spring24 is arranged upon the shaft 2 between the body portion 12 and sleeve21 to normally press them apart and hold the clutch members in clutchedrelation. Any suitable means for operating the lever 23 may be employedand other variations from the exact construction shown may be madewithout departing from the spirit and scope of the invention. I do notwish, therefore, to be understood as limit ing myself by the positivedescriptive terms employed, except as the state of the art may require.

Having thus described the invention, what I claim as new is 1. In ashaft-clutch, a member having a hub adapted to receive the shaft andbeing provided with a radially-projecting flange No. 813,869. PatentedFeb. 27, 1906.

To all whom it may concern: Be it known that I, MARTIN DEILLER, acitizen of the United States, residing at N ewr ark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Shaft-Clutches; and I do I hereby declare the followingto be a full, clear, f and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tofigures of reference marked thereon, which form a part of thisspecificat tion.

The objects of this invention are to provide a clutch adapted either totransmit motion from a rotary shaft to a pulley or the like upon saidshaft or to permit said pulleywheel to stand loose with relation to theshaft as desired; to enable the motion to be transmitted positively andwithout opportunity for slipping to obtain a clutch thus particularlyadapted for use with tobacco-stripping machines, as illustrated in myprior patent, No. 716,627, issued December 27, 1902; to provide such aclutch'which shall be always l under the immediate control of theoperator, and to obtain other advantages and results, some of which maybe hereinafter referred to in connection with the description of theworking parts.

The invention consists in the improved clutch and in the arrangementsand combinations of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the clauses of the claim.

.Referring to the accompanying drawings, in which like numerals ofreference indicate corresponding parts in each of the several figures,Figure 1 is a plan of a shaft having myimproved clutch applied thereto;and Fig. 2 is a side elevation of the same, certain of the parts beingshown in section. Fig. 3 is a cross-sectional view taken on line as,Fig. 2.

In said drawings, 2 indicates a shaft having adjacent to one end acollar 3, made fast thereon, as by means of set-screws 4. Adj acent tosaid collar is the loose clutch member 5, and at the opposite side ofthe same is the other clutch member 6, fast upon the shaft to turntherewith. The loose member 5 comprises a hub 7, having at its end nextthe other clutch member 6 a peripherally-projecting flange 8, providingat its side a series of ratchet-teeth 9. Upon the said hub 7 of theloose clutch member a wheel 10 is set by having a circular series ofteeth upon one of its sides, a second member having a crosspiece adaptedto be mounted directly upon the shaft and lie transversely thereofproviding opposite arms which project radially from the shaft, leversfulcrumed intermediate of their ends one upon each arm of thecross-piece and adapted to swing in the plane determined by said arm andthe shaft, each lever being adapted at its outer end or end farthestfrom the shaft to engage the said teeth of the first-mentioned member ofthe clutch and terminating at its opposite or inner end short of theshaft, and means for engaging said inner ends of the levers to swing thesame, one of said clutch members being adapted to be fast on shaft andthe other loose.

2. In a shaft-clutch, a member having a hub adapted to receive the shaftand being provided with a radially-projecting flange having acircularseries of teeth upon one of its sides, a second member having across-piece adapted to be mounted directly upon the shaft and lietransversely thereof, providing opposite arms which project radiallyfrom the shaft, levers fulcrumed intermediate of their ends one uponeach arm of the crosspiece and adapted to swing in the plane determinedby said arm and the shaft, each lever being adapted at its outer end orend farthest from the shaft to engage the said teeth of thefirst-mentioned member of the clutch and terminating at its opposite orinner end short of the shaft, a controllingsleeve on the shaft, andlinks substantially parallel to the shaft connecting the said inner endsof the levers to said sleeve, one of said clutch members being adaptedto be fast on the shaft and the other loose.

8. In a shaft-clutch, a member having a hub adapted to receive the shaftand being provided with a radially-projecting flange having a circularseries of teeth upon one of its sides, a second member having acrosspiece adapted to be mounted directly upon the shaft and lietransversely thereof, providing opposite arms which project radiallyfrom the shaft, levers fulcrumed intermediate of their ends one uponeach arm of the crosspiece and adapted to swing in the plane determinedby said arm and the shaft, each lever being adapted at its outer end orend farthest from the shaft to engage the said teeth of thefirst-mentioned member of the clutch and terminating at its opposite orinner end short of the shaft, a controllingsleeve on the shaft, a coiledspring adapted to surround the shaft between said cross-piece andcontrolling-sleeve, and links outside said spring and substantiallyparallel to the shaft connecting the inner ends of the levers to thesleeve, one of said clutch members being iidapted to be fast on theshaft and the other oose.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of November, 1904.
